Description

[Detailed description of the invention] The present invention accomplishes this by moving two separate members relative to each other in one axial direction. an axial lock for locking and unlocking these two members together; Relating to a locking device. This may require one-handed activation and/or quick activation of the locking device. It enables movement. One such axial locking device is disclosed in U.S. Pat. 4.709°454. The two parts are first pressed together locked at the same time, and then unlocked when the two parts are pressed together again It will be done. No relative rotational movement is required between these two members.

This axial locking device resists the axial force required to operate it. must be able to withstand unrelated tensile loads. This locking device is designed to be strong against tilting movements, i.e. with very small lateral forces. There is only a crash and the device is not designed to withstand large lateral loads. It is possible.

The present invention generally relates to an axial It can be applied to locking devices for the opposite direction.

The two separate members forming this device are each connected to an element that is connected together. or at least one of these members It can be made to be the element itself or form a part thereof. lock a portion of the second member engaged by a locking element of the stop member; and a locking mechanism. The portions of this second member that engage the actuating devices of the second member are They do not need to be integral with each other if they are indeed fixed.

In general, it is desirable to have inexpensive manufacturing. Also, relative motion causes members to move together. It is desirable to avoid conditions that would result in insufficient locking.

The locking device of the present invention can be applied to, for example, hoses, cables, electrical connectors, subassemblies, Momentary tightening or interlocking of panels, wires or mounting such as brackets can also be used to release small oil pipe connectors (e.g. (such as those that cannot be opened by applying pressure), connections to sewage equipment aerators connectors, flexible coupling connectors for instruments, medical life support couplings, gas meters. back connector of a motor, swimming pool coupling device or more of an automobile engine. Can be used for things like connecting devices. There is no relationship between the actuation force and strength of a locking device. There is no one in charge. This locking device must not be installed or removed in an inaccessible and blind location. Therefore, it is suitable for making connections in narrow and constrained places. Exercise is Since it is axial with no rotation, actuation can be performed even by a physically disabled person or by a simple person. It can also be easily performed by a robot, and one-handed operation is common. this lock The locking device is quick, cheap and simple.

The relative axial movement of the two members locks them together and This device provides an axial locking device that releases the a locking mechanism associated with a first member of the members; includes a device that produces a click actuation when it is partially or fully actuated. I'm reading. Multiple click actuations are required before locking. Will locking be done? , or produces a click actuation as long as it produces a return movement (opposite direction) or locking. Perfect operation is not necessary for this to occur. I can hear the sound (I can hear the click) It is desirable to have a click-actuated pulse or vibration while being held in the hand. The sensor can be arranged to be sensed by a member of the sensor. In this way, The click actuation informs the operator that the actuation point has been reached. here The term "click" refers to a physically perceivable audible sound or pulse (tactile feedback). Any suitable shock or mechanical activation action (mec feedback) It is also used to include hanical release), and this action is can be described as a snap actuation, thus the term "click" has an acoustic equivalent It includes.

In special arrangements to obtain a click actuation, a toothed sliding actuator a toothed rotating locking member when the material is moved axially; In cooperation, the teeth of the actuating member move axially (sometimes these teeth move the locking member with this the retainer by lifting it from its resting position against the retainer fixed to the housing of the device. The teeth on the actuating member rotate when the locking member is lifted away from the position. Rotate it so that it engages. This provides click actuation. Next, the operating part A spring device, e.g. a single spring, locks when the material is released and allowed to return to its normal position. Push back the slider on the stopper member and rotate the slider one tooth further until the tooth is Allow it to engage the retaining device again.

In contrast to the above, the retaining device can be arranged on the first member and the movable teeth can be placed on the housing to determine the relative position of the housing to the two members. The movement may cause actuation of the locking mechanism.

Click actuation can also be obtained in other ways.

In one method, a toothed rotor fixed to the locking means is axially two opposing lips of teeth each spring-loaded towards the rotor. It is rotated between the rings. In other methods, the rotational movement of the locking means is Arranged to be restrained by locking means cooperating with appropriate toothing on the housing When the spring force on this locking means overcomes the restraining force of the teeth, the lock is closed. The click means is arranged to fly up and provide a click action. like this The teeth do not necessarily have to be wavy, but wavy is the preferred shape.

In yet another method, the engagement of the two members locks the toothed locking means into the housing. The teeth are moved axially against the spring force relative to the teeth, thereby causing the teeth to When the teeth of the locking means precess in interaction with the teeth on the housing, the locking device when the teeth engage one set of the housing and then the other set. This is done so as to give a rotation of . The spring has a small number (one of the spring elements is It has a partially bistable effect, i.e. a click effect, when moving through a complete motion stroke. Can be made of single or multiple springs arranged to This is done so that a click action is applied to the operation of the locking mechanism.

It is desirable to include a locking member that is angularly movable. in the desired arrangement The locking means includes a rotating cam slider, and the rotating cam slider is e.g. Rotated by the interengaging teeth, the profile of the cam is shaped by one movement stroke of the teeth. the shape of which is changed within a recess or groove or other restraint disposed in the second member; At least one locking element inserted into or constructed from the Given the high and low parts of each cam, these in one direction This device is alternately operated by alternating cycles of relative axial movement of the two members. It is like locking and unlocking. In other arrangements, locking The element need not be made in a separate part from the locking means.

The slider is attached to or incorporated into one of these members and When a relative movement occurs between the two members, the slider moves against this member against the spring device. It is desirable that it be made to move relative to the other hand. This slider is one piece The interengagement of the mutually engageable teeth on the top and slider causes the slider to Each time it moves in the axial direction, it is moved in one angular direction. This corner of the slider A degree of movement occurs when two members are first moved axially against a force exerted by a spring device. locks the two members together when pressed toward each other, and then 2 when the two members are pressed axially toward each other against the spring force. This unlocks the two members.

Generally speaking, the device of the present invention provides a means for locking by the relative movement of said two members. a device for pressing the mechanism into actuation and a locking mechanism until said relative movement occurs; A retainer that prevents the mechanism from operating and allows this retaining action to be released by clicking.

It is desirable to The relative angular motion of the first and second angular thrust devices is the angular thrust device being restrained by engaging the first angular thrust device; The relative movement of the members in opposite directions causes the first angular thrust device to move into the second angular thrust device. releasing the force devices and further angular movement of these first and second angular thrust devices. It enables movement. The first thrust device and/or the second thrust device including teeth with beveled ends, such that these beveled ends provide an angular thrust; Eggplant is preferable. Preferably, this retainer is provided on teeth with beveled ends. , the first angular thrust device, the second angular thrust device and the retaining device teeth are locking devices. It is desirable to have sides substantially parallel to the axis of the position. This is the end of these teeth forming an angle to the sides and joining the sides at a point as shown in the cross-sectional view. However, in other structures, the first corner The progressive thrust device develops a radiused edge at the end. and the second angular thrust device has a V formed by a surface inclined with respect to the axial direction. shaped so that the end of the first angular thruster is at a large angle relative to the axial direction; for example 70°, and the retaining device partially or completely radially displaced from the angular thrust device of 1 and inclined relative to the axial direction. the surfaces, preferably alternating surfaces, are at the same angle as the corresponding surfaces of the second angular thruster. and the surfaces interposed between these surfaces respectively correspond to the second angular thrust device. by a surface formed at a larger angle to the axial direction than the surface that the intervening surface also cooperates with a second angular thrust device.

It is done in collaboration with.

A first angular thruster is arranged in the axial direction of the first and second angular thrusters. It is desirable that the pressure is applied in the opposite direction to the movement, and this pressing action is applied to the first and second The relative movement of the angular thrusters causes the first angular thruster to move in the axial direction. Let it move.

The second angular thrust device can be moved directly axially by the actuator. Wear. This second angular thrust device is an axis of an axially movable element. It is preferable that the holding device lies on the axial plane of the element movable in this axial direction. provided on or adjacent to the opposite axial surface, the retaining device being self-contained; The opposite movement of the body first and second angular thrust devices causes the angular thrust devices to The first and second angular thrust devices initially act as retainers. The relative angular movement of the retaining device is then prevented by a click action. This is done to allow angular movement.

For example, this Yet another actuator of the invention has teeth on each of the first and second rings. Further intervening rings of teeth may be included.

In U.S. Pat. No. 4,709,454, the locking mechanism is It has a pressing force of In a general sense, this pressing action is the pressing action of a spring. need not be, and this has been found to be the only practical means. Ru. A second feature of the invention is a variant with a spring-pressing action that is inexpensive to manufacture and assemble. This variant provides at least one spring-like protrusion. When there is relative movement between these parts, the spring element deflects and locks. This projecting element is arranged such that the locking means can be moved angularly. This element is Although it can be acted upon by a separate spring, this spring action is applied to the spring element itself. Preferably unique. This feature of the invention provides an extremely simple mechanism. However, this mechanism basically consists of a camshaft (in addition to the two separate members mentioned above). Only the rider and the locking element operated by this cam slider are needed This is not the case.

The device may include a restraining device that restrains the locking means when moved angularly. and the restraint device includes the first and second portions described above and has an angular orientation. The force is applied by this spring element.

From Figure 1 to Figure 3d In the embodiments of FIGS. 1 to 3d, the two profit elements 1.2 are both locked. locked and unlocked by an axial locking device. Ru.

The first part 1 has a locking mechanism, which locking mechanism is connected to the outer halves forming the actuating device. including a housing 3, the outer housing 3 being attached to the first member 1; is movable in an axial direction relative to this first member, but in an angular direction. In other words, it is substantially fixed relative to this first member l in the direction of rotation. outside this The movement of the side housing 3 is restricted by an annular flange 4 and an abutment ring 5. There is. As shown more clearly in Figures 3a to 3d, the first member 1 is an integral part of the tooth 6 with an inclined end (e.g. inclined at 45° to the axial direction) These teeth have an inwardly projecting retainer integral with the outer housing 3. It is designed to be able to move freely in the axial direction between the retaining teeth 7, and these teeth 7 also They have slanted ends facing in the same direction (preferably slanted at the same angle). child These teeth 6 are substantially fixed relative to the teeth 7 in the direction of rotation.

A cam slider 8 is disposed within the outer housing 3, and the cam slider 8 is rotatable around the axis of the locking device, and this cam slider 8 integral part of the tooth 9 having at one end an inclined end facing away from the ring of teeth 6,7; rings, the ends of which are inclined at the same angle as the ends of the teeth 6.7. It is desirable that All teeth 6.7.9 have the same pitch, but teeth 6,7 The width is half the width of tooth 9. All teeth 6, 7.9 are on the axis of the locking device have parallel sides.

The other end of the cam slider 8 has a wavy cam contour on its inner periphery as shown in FIG. Cultivate a state of mind. This cam profile has two or more spherical 10-shaped locks. These spheres lO are adapted to cooperate with the stop elements in the outer housing 3. is retained in a return skirt integral with the second part. This locks the second member 2 with respect to the first member l by engaging within the annular recess 11 in the member 2. It is possible to stop it. These locking balls 10 are rotated by the cam slider 8. It is adapted to be actuated by the cam profile in relation to its position. This cums The rider 8 is pushed in one direction against the housing 3 with a constant force by a spring 12. Although under pressure, this spring 12 is between teeth 7 and 9, i.e. between teeth 7 and 9. It is designed to work effectively between each fixed part.

Upon actuation, the members 1.2 are moved axially in a first direction relative to each other. An abutment ring 5 on the housing 3 engages the second member 2 when the housing 3 is moved. this resting position The arrangement is generally shown in FIG. 3a, with a small gap between the ends of teeth 6.7 and 9. Even between the ends of the teeth, these teeth are brought into mutual engagement.

Teeth 6.9 provide first and second angular (i.e. rotational or circumferential) thrusts. It acts as a device. Movement of the first member I in the direction of the arrow in FIG. Considering that, when the abutment ring 5 engages the end of the second member 2, the tooth 6 Push back the tooth 9 as shown by the arrow in the figure and thus push back the cam slider 8 The mutual engagement of teeth 6, 9 then forces the locking mechanism towards the actuated position, with tooth 7 It is held stationary by the abutment of the end of the member 2 with the ring 5. This movement is Until the side surface of tooth 9 separates from the side surface of tooth 7, that is, the top of tooth 9 becomes the top of tooth 7 ( acting as a retainer) until the tooth 6.9 is separated from the The cam slider 8 is rotated, but in this case, the cam slider 8 is rotated by the action of the spring 12. to the left in the axial direction, and the side surface of the tooth 9 is moved axially to the left by the tooth 6, as shown in FIG. 3c. acoustic or tactile lick or snap action. This results in a temporary half-wave stable position that is sensed by the current. At this position, lock the Although the sphere lO is not fully expanded, these members l.

It expands enough to lock the two together.

The relative rotational movement between the teeth 6.9 causes these members 1. In the one direction of 2. It is energized by a spring 12 which is compressed by the relative movement of the two.

When the first member 1 is moved to the left, the teeth 6 are in the original position as shown in Figure 3d. It is pulled towards. Once the tooth 6 is disengaged from the side of the tooth 9, the inclination of the tooth 7.9 The beveled end acts as an angular thrust device, and the cam slider 8 finishes its rotation and the third a As shown in the figure, a click is applied to the position where the side surface of tooth 9 comes into contact with the side surface of tooth 6 again. Or perform a snap action. The sphere 10 is now fully expanded and this locking device is It is completely locked.

Some relative movement in said one direction occurs between these members 1.2; This causes the holding action to be released until the holding action is released by a snap or click action. , the tooth 7 is a retaining device that prevents the activation of the locking means, that is, the rotation of the cam slider 8. It works as a station. Hold tooth 9 until click or snap action occurs. The retaining device 7 does not have to have beveled teeth, although beveled teeth are desirable. It can be made into a new shape, for example a rounded pin. Similarly, teeth 6 is a rounded edge or other contour shape (see Figures 4 to 5d) can have. Alternatively, if the teeth 6, 7 have beveled ends In other words, the teeth 9 can be made into projections of different shapes.

The spring 12 is arranged around the cam slider 8 and the diameter of the locking mechanism (as shown in FIGS. 8 to 9d) similar to the arrangement shown in the example) but even smaller in the axial direction. It can be made into a mold.

This locking device prevents the complete return of the housing 3 and cam slider 8 after actuation. It relies on the inertia or retraction action of the first member I to do this, but if If a fully automatic return action is desired, a light wave spring is applied to the flange 4 and tooth 6. The housing 3 can be provided between the housing 3 and the housing 3 so as to press the housing 3 to the left.

From Figure 4 to Figure 5d The axial locking devices in Figures 4 to 5d are generally shown in Figures 1 to 3d. Similar to what was shown before, but with teeth 6, 7 and 9 shaped differently, The teeth 6 are partially radially displaced from the teeth 7, as shown in FIG. It is adapted to protrude through the notch of the tooth 7. Teeth 6 have rounded ends. radiused edges so that these ends are axially The surface is formed at a large angle, for example 70°, with respect to the surface. Teeth 7 are V-shaped or The teeth 7 are arranged in a zigzag shape, with each tooth 7 being inclined at a different angle to the axial direction. The leading surface (with respect to the direction of rotation of the slider) is An angle to the axial direction that is smaller than the angle to the axial direction of the subordinate surface, i.e. For example, it is inclined at an angle of 42° to 24°.

Teeth 9 are V-shaped or zigzag-shaped, with alternate faces or opposite directions with respect to the axial direction. are inclined at the same angle, for example 42°.

Operation is generally similar to the device of FIGS. 1 to 3d. The abutment ring 5 is the second When engaged with the end of the member 2, the teeth 6 are connected to the teeth 9 and thus to the cam, as shown in FIG. 5b. The slider 8 is pushed back, but due to the interaction between the curved edge of the tooth 6 and the inclined surface of the tooth 9, the slider 8 is pushed back. The muslider 8 is rotated and the mutual engagement of the teeth 6° 9 moves the locking mechanism toward the activated position. However, the sliding sides of the teeth 7 and 9 prevent the gradual rotation of the cam slider 8. Make it stop. This movement causes the cam slider 8 to rapidly rotate as shown in Fig. 5C. engaged with the other edge of the tooth 6 as shown to produce an acoustic and tactile click or or slightly to the left by the action of spring 12 until it develops a snap action and is restrained. The movement continues until it separates from the side of tooth 9 or the side of tooth 7. first When member l is moved to the left, tooth 6 is retracted into its original position as shown in FIG. 5d. The side of tooth 9 slides down the edge of tooth 6, slides down the side of tooth 7, and slides down the side of tooth 6. During the retraction operation, the top of tooth 9 moves along the beveled edge of tooth 6. . Depending on the exact contour of the tooth 6, the tooth 6 can be completely pulled into the position shown in FIG. 5a. A small click can occur when loaded. With this, the sphere 10 When the locking device is fully expanded, the locking device is completely locked.

The device of FIGS. 4 to 5d provides an automatic return movement of the cam slider 8. .

Figures 6 and 7 The axial locking device of FIGS. 6 and 7 is very similar to that of FIG. and further for operating the locking mechanism to lock and unlock. a device, which device can be moved without relative axial movement of the separate members 1, 2. It is mainly used to release locks. This modification form can be canceled externally. or allow emergency actuation, in which case no axial movement of parts 1, 2 is obtained. However, these members 1 and 2 are separated. housing extension A length 21 is formed in the housing 3 and includes an auxiliary actuating slider, i.e. a slider. forming an end stop for the blade 22 and an abutment for the second spring 23. is forming. A groove 24 is formed in the housing 3, as shown in FIG. An auxiliary tooth 25 protruding toward the side protrudes through this groove 24, and the teeth 6 and 7 are interposed between the teeth 6 and 7. It is now being accommodated.

By pressing the sleeve 22 to the right, the auxiliary tooth 25 causes the tooth 6 to move the tooth 9 to the third C. Push back the tooth 9 in the same way as shown in the figure, but the tooth 6 is between the parts 1.2 Since there is no relative motion, it remains stationary. In this way, Muslider 8 does not interfere with the main locking element and can be used outside of the locking device. It is possible to perform precession.

From Figure 8 to Figure 9d The axial locking devices in Figures 8 to 9d are similar to those in Figures 1 to 3d. The function is similar to that of . In this case, the first member l forms the outer housing. , an actuating device is provided on the abutment member 3, which abutment member is axially aligned with respect to the first member l. direction, but substantially rotationally movable with respect to this first member l. is fixed and grows integral projecting teeth 6, which teeth 6 of the first member l. It is designed to pass through an axial groove cut in the inner wall. Tooth 7 is the first member It is made integral with the inner wall of 1. The teeth 9 are integrally formed with the cam slider 8. There is. The cam slider 8 has an outwardly projecting flange 31. 1 forms a contact portion for the spring 12. Overall, this locking mechanism so as to leave a larger area for spring 12 than that shown in FIG. However, this place is wide and short.

The operation of this embodiment is similar to that shown in Figures 1 through 3d, except that In this case, the second member 2 is movable and the first member l is fixed. .

The housing forming the first member 1 is a rigid assembly with a flange (not shown) or terminates in a male or female profile. This example is shown in Figures 6 and 7. Develop an auxiliary slider for external actuation as shown in its entirety in can be modified to

In the embodiments of FIGS. 1 to 8, the locking mechanism is , the sphere 10 is configured to be able to expand outward without expanding inward, The locking mechanism is arranged in the male member instead of in the female member (e.g. (See Figure 16 or Figure 22).

The embodiments shown in Figures 1 to 8 form simple structures with a relatively small number of parts. has been completed.

From Figure 10 to Figure 11b In the embodiments from Figures 1θ to 11b, the first member l is a corrugated restraint. Or an integral engagement element in the form of teeth 41 (see Figures 11a and 11b). It forms a housing with. The teeth 41 are integrally formed with the end of the cam slider 8. to interengage with complementary corrugated elements in the form of restraints or teeth 42 formed. ing.

These teeth 41.42 are arranged so that when these teeth 41.42 are fully engaged, It provides a stabilizing or inhibiting effect at predetermined intervals in the direction of the For more information, see When a relative axial movement occurs between the member 1 of 1 and the cam slider 8 Only when the relative angular movement of the first member! (forming the first part of the retaining device) ) and the cam slider 8 (forming the second part of the retaining device). It is done as it occurs. The rotational force applied between the teeth 41 and 42 is due to the cam engagement. This results in relative axial movement due to the synergistic action.

The pressing or springing device is different from that described above. The pushing device is also an angular thrust device. The spring element (crotch, tab or contains 43 rings (which can be referred to as teeth).

These elements 43 are made obliquely with respect to the axis and direction of rotation of the locking device. It is slanted. The remote or free ends of these elements 43 are integral with the ring 3 engaged by a recoil device in the form of a series of ratchet-like or serrated teeth 44. However, this ring 3 acts as an abutment ring and as an actuating device, respectively. The teeth 44 are arranged in a plane parallel to the axial direction and at an angle of, for example, 8° to 16° with respect to the axial direction. It has a surface that forms an angle at . This ring 3 is secured to the first part by a small lip 45. is held in a housing forming a member 1 and is attached to the first member l, e.g. keyed by a tab 46 or an outer or inner spline to the first member. It is adapted to move within a short axial groove in the l.

This arrangement results in a relative movement between the parts 1.2 and the abutment ring 3 shown in FIG. 11b. Spring element 43 when moving to the left as shown by the arrow with one head in is locked within the reaction tooth 44 and is not compressed, circumferentially bent or deflected. and the cam slider in the direction indicated by the two-headed arrow in Figure 11b. 8, i.e. pushing the locking mechanism towards the actuated position. So do it. However, the cam slider 8 is temporarily , and a significantly greater force is applied to the spring element 43 (as shown in FIG. 11b). (in the position in which the spring element 43 is moved by one pitch of teeth relative to the first member 1) The cam slider 8 is prevented from rotating until it suddenly starts flying. When rotating, the pressing force in the rotational direction by the spring element 43 decreases, and the There is a slight tendency to fly over the sky. cam slider teeth When the tooth 42 passes over the top of the tooth 41 with a snap action, a dull click action occurs. Ru. The permissible rotational movement is greater than the pitch of half a tooth, but the pitch of one tooth is Must not be exceeded. The geometry of the spring element 43 and the reaction tooth 44 corresponds to the abutment lip. When the ring 3 is forced completely to the left, the cam slider 8 moves one of the reaction teeth 44. It is shaped so that it moves forward by a pitch.

The abutment ring 3 is restored by moving the parts 1.2 away from each other in the other direction. When returned, the spring element 43 straightens and the spring action returns the abutment ring 3. When the spring elements 43 return to their original tilted position, these spring elements 43 jumps by one tooth 44 and engages in the recess of the new reaction tooth 44. 1st As shown in figure 0a, the end of the spring element 43 is connected to the top of the tooth 44 in the rest position. It engages approximately half way between the two. Teeth 41 and 42 are appropriately phased. There is. The locking sphere lO is now fully expanded.

The working stroke of the cam slider 8 and the interaction between the spring element 43 and the teeth 44 are , the spring element 43 causes the tooth 42 to move to the next tooth 4 when the relative axial movement is reversed. 1 just enough to rotate the cam slider 8 just enough to engage the cam slider 8. This is done in such a way that it has a component of radial motion. as mentioned above , the cam slider 8 has an angle slightly greater than half the pitch of the teeth 41.42. must be rotated, and must not be rotated by more than one pitch. do not have. This gives significant leeway. The tops of teeth 41 and 42 are separated from each other. When separating, the bending of the spring element 43 acts as a spring at this point and straightens it. The cam slider must be sufficient to allow the cam to rotate sufficiently during this time. The tops of the teeth 41 and 42 pass each other, and once the relative axes are aligned. The locking device engages the next tooth 41, 42 when the direction movement is reversed. We perform a pulling out exercise. At this point the spring element 43 still engages the tooth 44 and reverses The friction of the spring element 43 against the teeth 44 causes the cam slider to move when the relative movement occurs. Sufficient force must be applied to hold the holder 8 within the range of the next tooth 41. No. Therefore, the bending of the spring element 43 simply causes the cam slider 8 to undergo a new rotation. Just enough to press into position, but also allow the tops of teeth 41.42 to pass The formation of a straightening force that holds the distal end of spring element 43 against the side of tooth 44 until must have a certain amount.

The spring element 43 is always activated even when the locking device is fully relaxed to the inoperative state. It must be long enough to contact some portion of the tooth 44. Of course The operating speed must be just the right speed, but it is similar to the striking action of a hammer. Such operation may cause the cam slider 8 to fly over teeth 41 and 42. It happens.

The cycle is repeated to provide alternating camming surfaces to the locking sphere 10 so that these When the sphere is allowed to be retracted and parts 1 and 2 are completely separated, the lock is activated. The locking device remains locked until a relative movement in the original direction occurs again between the parts 1.2. It remains in that state.

The spring element 43 must not be stretched beyond its elastic limit. This means that the contact The ring 3 is flush with the right end of the housing formed by the first member l. This is conveniently done by allowing the abutment ring 3 to reach its limit of motion when be able to.

The spring element 43 and the cam slider 8 are made of plastic material, for example carbon fiber. Can be made by injection molded nylon with fiber reinforcement. Is it extremely high temperature? In special cases such as low-temperature environmental conditions, the spring element 43 is connected to the cam slider 8. is injection molded into the slider 8 of a different material, e.g. , or by steel alloy parts that are later assembled and held together, e.g. by shrinkage action. can be made.

For example, if the tooth 44 is sufficiently inclined, the spring element 43 will parallel to the line, the element 43 is compressed and bent along the inclined surface of the tooth 44 It can be done like this.

The recoil device preferably formed by teeth 44 must develop a shape as described above. For example, just a ring of small radial ridges, or just a rough surface or Figure 12 shows the actuating device. 3 is made into an inwardly projecting lip integral with the cam slider 8, and the member 1.2 When the cam slider 8 is moved toward the member 1, the cam slider 8 is moved to the left relative to the member 1. 2 shows an axial locking device which is adapted to be moved directly in the direction shown in FIG. this This means lifting the V-shaped teeth 41, 42 apart (see Figure 13b) and The teeth 41, 42 of the cam slider 8 initially act as a deterrent to prevent the new rotation. The cam slider 8 is prevented from rotating when moved into position, and the teeth 41 The 42° plane is inclined at 30° with respect to the axial direction. Teeth 41. The depth of engagement of 42 and its contour shape are such that rotation of the cam slider 8 is caused by tooth 41.4. By pressing the two sides together, the teeth 41 and 42 are released from the locked state by a click action. The cam slider 8 is designed to fly rapidly when detaching (Fig. 13b). . As in the embodiments of FIGS. 10 to 11b, the spring element 43 and the The geometry of the movable tooth 44 is such that the abutment lip 3 is forced completely to the left (Fig. 13c). When the cam slider 8 is moved forward, the cam slider 8 moves forward by the pitch of one reaction tooth 44. It will be done. When the abutment lip 3 is returned by the return movement of the member 1.2, The spring element 43 returns to the original position without applying any effective rotational force to the cam slider 8. The rotation of the cam slider 8 is normally controlled by a friction device. This is prevented by the engagement of the abutment lip 3 against the member 2. cam The slider 8 moves forward by the pitch of one reaction tooth 44, and the locking ball lO is completely moved forward. When expanded, the locking device is fully locked. Figure 13d is element 43 cam slider 8 moves immediately before the cam slider 8 clicks into its new tooth recess. It shows. This cycle is moved so that parts 1 and 2 are brought closer to each other again. This is repeated when the locking device is released. Figure 13a is at rest. The layout is shown here.

Merely as an example, FIG. 12 shows the configuration of a fluid conduit sealed by an O-ring seal 51. 1 shows members 1 and 2 made into a shape. The overall arrangement is electrical connectors or Suitable for liquid or gas coupling devices.

Figure 14 The teeth 41,42 have other shapes, for example sinusoidal or semicircular shapes with a large radius. - A smoother wave shape has fewer critical engagement points but is more gentle. It gives a gentle effect.

FIG. 14 shows a modification of the device of FIG. 12, but in this case the teeth 4142 are shaped and has a significantly smaller top-to-recess distance.

Figure 15 Figure 15 shows a device similar to that of Figures 12 or 14, but with cams. It has a cap-shaped contact device 3 that is integral with the rider 8. overall arrangement is suitable for mechanical tightening devices.

Figures 16 and 17 Figures 16 and 17 correspond closely to Figure 15, but within the male member l. The locking mechanism is shown. The actuation or retention device projects through the end of the male member 1 When the male member l engages with the female member 2, the male member l is They are adapted to move relative to each other in the axial direction. Figure 17 is a pitch circle or small diameter Spring element 43 shows the closer tooth pitch required for growing whose bending shape extends over the greatest part of its length to reduce local stress. A long life design is possible if it is made to last. Two such designs 18 and 19 and may be applied to any suitable embodiment. Ru. The element 43 has a circular cross section and is shaped like a circle to follow the curve of the restraining member 1 or 3. It is slightly bent in the circumferential direction.

The number of spring elements 43 can be reduced to two or three to improve sturdiness and resilience. benefits can be obtained in terms of gender, and this number is similar to that shown in any of the examples. There's no need to do it. For example, the number may be such that the teeth 44 are made the same and the first The number of spring elements 43 in FIG. 7 can be reduced to half.

From Figure 20 to Figure 21c Figure 20 is basically the locking device of Figure 13 of U.S. Pat. No. 4,709.454. A similar axial locking device is shown, which requires a detailed description. There's no need. The cam slider 8 is made into a sleeve. The actuation or retention device is The disc 3 is integrated with one end of the cam slider 8. this disc 3 The flange is shaped like a flange and has an annular part that protrudes beyond the cam slider 8. There is an annular set of teeth 61, 62 on each axial surface of the tooth. The annular set of teeth of is made integral with the first member l or is fixed to the kneading member. , each adapted to engage an annular set of opposing teeth 63,64. teeth The interengaging set of 61, 63 and 62° 64 rotates the cam slider 8 useful for. When the cam slider 8 reciprocates back and forth, the cam slider 8 Performing precession motion as shown in Figures 21a to 21c in rotational motion. It is.

The pressing device of the cam slider 8 is a snap-acting disc-shaped spring that is coaxial with the locking device. It is made in the form of 65.

This characteristic is that this spring 65 normally holds the cam slider 8 in the right position. , when pressed to the left, the spring 65 is flattened and the negative side is removed from its convex shape. Provides click action when converting the side to a convex shape and maintains the pressing force to the right. It is made to hold. This gives an acoustic lick actuation and also a second provides a tactile feedback effect on the member 2.

Figure 22 Figure 22 shows how the arrangement of Figure 20 can be applied to the first male member 1. The device shown in Figure 22 is similar to that shown in Figure 15 of U.S. Pat. No. 4,709.454. It operates on the same principle. The locking balls 10 are a pair of locking balls. Extended reach by inserting a short plunger element 71 between the bodies 10 given a range.

FIG. 22 also shows that an auxiliary spring 72 can be combined with spring 65 if desired, particularly for cams. It shows what has been done to give the slider 8 an extremely long movement. Spring 7 2 is placed in the countersink of the cam slider 8.

Figure 23 is similar to Figure 15 of U.S. Pat. No. 4,709.454 in general principle. Fig. 2 shows an axial locking device similar to that shown in Fig. 1. This embodiment was made lightweight In an embodiment, the first member 1 has a small outer diameter, such as 4B, and is a small linear A latching portion is formed.

This locking mechanism is shown to be assembled to the male member 1, and the male member 1 is shaped like a bowl. It is adapted to be locked onto the female member 2. The male member I has an swaged end. operation The device is made on a rod 3 which has two bushings for the member 1. or is guided in a sliding motion by the stator 81.82, These bushings are secured within part 1 by means of swage locking rings. mosquito A roller 83 is fixed to the distal end of the rod 3 and forms an abutment for the return spring 12. ing. This rod 3 supports a rotor 84 in its central portion, and this rotor 8 It is fixed at 4. The front end of the rod 3 is fitted with a locking device or an angularly movable lock. It acts as a stop member or cam slider 8, and the rotation of the rod 3 is caused by the locking ball l. Locking sphere 10 is attached to member 2 by providing alternating high and low points of the cam relative to O. It is designed so that it can be secured to the restraining part 11 formed by the upsetting annular part inside. .

The rotor 84 cooperates with a respective ring of teeth 6.7 on the bushes 81.82. It has a ring of 9°85 beveled teeth facing opposite sides.

The teeth 6 and 7 of the bushes 81 and 82 are pressed in opposite directions in the axial direction by spring force. It has a special structure like this. The bushes 81 and 82 have serrations. There is.

These serrations are such that each bush 81, 82 corresponds to the rim of each tooth 6, 7. between the locking ring and the locking ring to which the bushing 81.82 is fixed. As long as it has a following part in the direction, it can have a cedar leaf pattern shape or a zigzag shape as shown It can be made into any suitable shape. These bushings 81.82 are suitable It can be made of any suitable plastic material.

Due to the arrangement described above and the appropriate spacing between the bushings 81,82, the axial The opposite locking device is in principle similar to that in Figure 15 of U.S. Pat. No. 4,709.454. They can operate in exactly the same way. Insert the female member 2 in the direction of the arrow shown in FIG. By moving the teeth 6, 9 in the (using the terminology), the rotor 84 has its teeth 9 engaged with the teeth 6. It is. This causes the tooth 6 to press against the fixed spring pressing force of the bush 81. However, the relative rotational movement is caused by the lateral side of the tooth 7.85 acting as an auxiliary device. The mutual engagement forces the locking mechanism towards the activated position.

When the top of the tooth 85 separates from the top of the tooth 7, the rotor 84 is moved so that the tooth 9 completely joins the tooth 6. It rotates until it clicks into full engagement.

When the movement of the second member 2 is reversed, the main return spring 12 pushes the rotor 84 back. , this must be stronger than the splashing action provided by Bush 81. stomach.

A similar snapping action or click occurs when the top of tooth 9 separates from the top of tooth 6. action occurs, in which tooth 7.85 acts as the first and second angular thrust device. , the teeth 6°9 act as an auxiliary device.

From Figure 24 to Figure 28 24 to 28 show variants of the use of the sphere 10 as a locking element. are doing. In Figures 24 and 25, the axial direction is to the left across this page. The top of the illustrated locking element corresponds to the cam outline of the cam slider 8. is engaged in. Figure 24 shows a flat T-shaped tab or slipper 91. , FIG. 25 shows a T-shaped tab with a rounded head, i.e., a slipper 92. ing.

Figures 26a and 26b show arrangements that can be incorporated into Figure 10, for example. ing. Figure 26a shows member l.

2 shows the locked state, and Figure 26b shows the unlocked state of member 1.2. It shows the status. The locking element is integral with a thin-walled deformable tab ring 94. Lugs or tabs 93, but this tab ring 94 is made of plastic or or elastic metal. The tab 93 is attached to the top of the female first member l. It is shown protruding through the hole in the housing. However, unlike the above, As shown in FIGS. 27 and 28, the tab ring 94 has a continuous wall. Thin walls with split skirts (Figure 27) or thick walls with split skirts (Figure 27) Figure 28) may be adapted to form a female first housing. Wear. The cam slider 8 is a ball or roller 95 as shown in FIG. 26a. Can be provided with an axial groove built in, or simply a raised cam protrusion can have.

Does this arrangement provide for a locking ball 10 projecting through the wall of the first member 1? This arrangement also reduces cost and simplifies design. It can simply be done.

General Parts 1, 2 can be solid parts, or one can be tubular and the other solid. , or both can be made tubular. If both of these members are tubular, If there is a gap between these parts, or one has an extension, and this can be slipped into the other with a suitable fluid seal or electrical plugs and sockets for optical connections or for optical fiber chain connections An integrated device can be provided. Corresponding to this, the contact member 3 in FIG. An opening can be formed through the center of the opening (see Figure 12).

However, the locking device may also be used as a simple releasable fastener.

For example, an electrical plug and socket connection allows an electrical bottle to be attached to a locking device. centrally located and locking devices placed around the outside of this electrical bin. An additional locking device formed as a locking device, which can be It is also possible to install a pin.

A small return movement occurs during locking. This kind of return movement is caused by electrical connectors - or undesirable for optical fiber connections. One way to avoid this is The method is such that the male and female elements are completely pressed together by friction when making the connection. The purpose of this is to ensure that it is maintained in a stable condition. When these things are pulled, are only separated by a defined return distance, after which both elements are stopped. It is. In different configurations than those mentioned above which are desirable for coupling optical fibers. The locking device wraps around the connector and slides axially relative to the connector. It is made in the form of a possible sleeve. This connector faces the sleeve When the sleeve is pressed by the spring, the connector returns completely to its original position ( g.

home), even if the sleeve makes a return movement, it is completely retained in its original position (re main home).

In different applications, two of the locking devices of the present invention (e.g., FIG. 23) may be Used to latch quick tightening/releasing devices to pewter cables This locking/releasing device can be connected to an axial lock at the foot of each leg. It is made into a shape with a device, that is, a bridge. Yoke is sufficiently elastic The computer cable connector is completely removed by the return movement. This allows it to be held in place.

Figure 29 More generally, locking devices are used to secure items, for example, against a fixed point, such as a bulkhead. It can be used for tightening, in which case the hole in the fastening part itself acts as a female member, and A bushing or eyelet device is provided on the fixed part to act as a male or female part. Can be made as a brout mount or flush mount d mounting 0rflush mounting) shall be provided. and the member releasable from the fixing part has male or female threads, or any suitable type of fastener arranged to effect a mating or threaded fit. Can be provided.

The female member l is attached to the fixing part 102, for example, with a snap ring 10. 3, and is made almost flush with the front (right side) or fixing part 102. It is.

The male member 2 is necked and passes through the panel 101 in a loose fit, and the compression spring 10 5 and supports a head 104 which is captured between the panel 101 and the panel 101. pa When the channel lO1 is brought to the fixing part 102, the engagement occurs as shown in FIG. It is done, but it is not fully latched. The end of the male member 2 is a spring 105 When pressed against the action of the locking device is latched and the panel 101 is installed. It is made to be preloaded by the force of the spring 105. child The arrangement of the panel lO1 causes a large number of objects that cannot all be engaged at the same time due to the movement of the panel lO1. Suitable for large panels 101 with tightening devices. As shown, the panel The lever 101 is dished at the position of the locking device, and all the locking devices are latched. The exposed end of the locking device is substantially flush with the exterior surface of panel 101 when It will be done.
