System for assembling a device, in particular a medical device, with a support

Description

Technical Field

[0001] The present invention relates to the technical field of fixing systems allowing an electronic device in the general sense to be temporarily secured to a support.

[0002] The present invention finds applications in many industrial fields but it is aimed more particularly at the medical field where a medical electronic device is to be temporarily hung on a support, such as an IV pole or a solute rod for example.

[0003] The subject of the invention finds a particularly advantageous application in the field where the electronic medical device is a display screen used with a medical device, such as an endoscope, this screen being intended to be temporarily suspended during use of the endoscope.

[0004] A medical endoscope in the general sense allows access to the interior of a hollow organ, a cavity or a natural or artificial conduit of the human body in order to carry out various operations for therapeutic, surgical or diagnostic purposes. Prior art

[0005] Generally speaking, an endoscope comprises a control handle in the form of a housing adapted to be held by a user of the endoscope and to which is attached a tubular structure designed to be inserted into a body cavity of a patient to be examined. This tubular insertion structure comprises a distal head equipped with a vision system for illuminating and examining the organ, cavity or duct of the human body. Upstream of the distal head, the tubular insertion structure comprises a deflecting portion controlled by a mechanism of the control handle to orient the distal head inside the insertion path. In order to visualize the interior of the hollow organ, cavity or natural or artificial duct of the human body into which the endoscope is inserted, the endoscope is connected to a display screen on which the images from the vision system are displayed.

[0006] Fixed viewing screens are very common: these are screens fixed to the wall of the operating room, for example. The stability of these screens is then guaranteed. However, in order to perform an endoscopy, it is essential to be in a room equipped with a fixed viewing screen. In a hospital or clinic, this requires either equipping all rooms with viewing screens, or limiting endoscopy to certain rooms. This is why it is advantageous to have a mobile viewing screen.

[0007] Mobile display screens are also known. These include floor-standing screens that can be placed on a tabletop in the operating room. Depending on the size and weight of these screens, moving them is not always easy.

[0008] In particular, there is the mobile viewing screen marketed by the company AMBU ®< under the name AVIEW ™<, which is mobile and compact. This viewing screen has the advantage not only of being able to be placed on a surface, but also of being able to be fixed to a solute rod. For this, the viewing screen has on its rear face a screw fixing system comprising a hoop, one of the branches of which is equipped with a screw, the tightening of which on the solute rod allows the screen to be suspended while being able to adjust its position relative to the rod. To make the screen easily detachable from the screw fixing system, the back of the screen is provided with a slide intended to cooperate with a complementary slide arranged on the screw fixing system.In practice, it turns out that the assembly and disassembly of the screen are relatively delicate operations to carry out because they require the slide on the back of the screen to be perfectly aligned with the slide on the support. Apart from these handling difficulties, the assembly and disassembly operations are accompanied by a significant risk of the screen falling and consequently damaging it.

[0009] Also known from patent application US 2019 / 154190 is a system for mounting an electronic device on a vehicle. This fastening system comprises a fastening part secured to the electronic device and comprising projections and grooves arranged alternately. This system also comprises a locking cap provided with a projection and a rotating cap having a groove and mounted rotatably relative to the locking cap. The support is fixed to the fastening part by inserting the projection of the locking cap into a groove of the fastening part and rotating the fastening part relatively to the locking cap. During this rotation, a tab of a locking member cooperates with the groove of the rotating cap, preventing the removal of the locking cap relative to the fastening part.Such a mounting system has a relatively complex and bulky design with a locking member protruding from the electronic device for operation.

[0010] Patent application US 2014 / 360893 relates to a device for mounting a protective shell of a portable electronic device on a support. This protective shell has in its rear wall, a housing delimited by spaced teeth and in which is inserted a locking element provided with tabs which, after rotation, are blocked behind the teeth of the protective shell. Such a device also has the disadvantage that the unlocking element protrudes from the electronic device in order to be actuated.

[0011] Patent application US 2015 / 136933 describes a connection system for removably mounting a portable electronic device on a flat surface. This system comprises a male connector provided with teeth intended to engage in a female connector having housings of a shape complementary to the teeth. A relative rotation of the male connector with respect to the female connector allows for a connection between them. However, such a connection system does not ensure secure immobilization and rotational immobilization of the portable electronic device with respect to the flat surface. Statement of the invention

[0012] The present invention therefore aims to remedy the drawbacks of the state of the art by proposing a new removable assembly system designed to allow easy assembly and disassembly of a device on a support, these assembly and disassembly operations being able to be carried out in complete safety for the device.

[0013] The present invention also aims to propose a new removable assembly system designed to allow, with a single hand, the assembly and disassembly of a device on a support.

[0014] To achieve such an objective, the system according to the invention aims to ensure the removable assembly of a device with a support, using a male part equipping the support and cooperating with a female part equipping the device: the male part comprising an arm having a free end provided with a series of support teeth extending radially in a radial plane while being distributed according to an angular distribution; the female part comprising at least one locking plate delimited by a front face and a rear face and in which is arranged an opening of section adapted to allow, in an insertion position, the engagement from the front face, of the free end of the male part beyond the rear face, the opening arranged in the locking plate delimiting retaining teeth extending radially and which, after a relative rotation between the female part and the male part, are capable, in a locking position, of coming opposite a support tooth to prevent the disengagement between the male and female parts, from the rear face in the direction of the front face;the female part and the male part comprising an angular locking device capable of angularly locking the female and male parts when they occupy the locking position, the angular locking device comprising a latch mounted radially movable on the rear face of the locking plate and provided with a translational displacement member accessible from the front face of the locking plate, the latch being intended to automatically engage in a stop groove in the external edge of a support tooth; the female part comprising a stop bottom for the male part limiting the engagement of the male part beyond the rear face of the locking plate and having a rotational guide surface between the male part and the female part in order to move from the insertion position to the locking position and vice versa. ;

[0015] In addition, the system according to the invention may include the following additional characteristics: the stop bottom comprises, as a rotational guide surface, a circular stud of conical shape; the male part comprises a number of support teeth equal to the number of retaining teeth of the female part; the support teeth of the male part and the retaining teeth of the female part are regularly distributed angularly; two adjacent retaining teeth of the female part delimit between them a passage notch for a support tooth of the male part while two adjacent support teeth of the male part delimit between them a passage hole for a retaining tooth of the female part; the angular width of a passage notch taken between two adjacent retaining teeth is equal to a value between 105 and 200% of the angular width taken for a support tooth; the external edge of the support teeth comprises, from each of its ends, a support ramp for the latch opening into a stop groove of the latch;the latch is elastically biased in extension by a spring member in its maximum extension position so as to be progressively compressed when it is supported on the ramp of the external edge until it automatically engages in the stop groove; the latch is intended to automatically engage in a stop groove of the external edge of a support tooth under the effect of its own weight; the latch is mounted to extend vertically in line with the middle of a retaining tooth arranged in the locking plate. ;

[0016] Another object of the invention is to provide equipment comprising an apparatus assembled with a support using a removable assembly system in accordance with the invention.

[0017] According to an advantageous embodiment variant, the device comprises a housing with a rear face provided with the female part of the assembly system, the male part of which equips the support. Advantageously, the rear face of the housing of the device is provided with the member for translational movement of the locking latch, positioned near the upper edge of the housing.

[0018] According to a preferred application, the device is a display screen for a medical endoscope.

Description of the embodiments

[0021] The subject of the invention relates to a removable assembly system 1 for ensuring a removable assembly of a device 2 on a support 3 of any type known per se. According to a preferred application, the support 3 relates to the medical field. For example, the support 3 may be a medical accessory commonly called an IV pole or IV pole. Of course, the support 3 may be produced in a different manner, such as in the form of a piece of furniture or a trolley. The support 3 is shown diagrammatically in the drawings in the form of a cylindrical body for illustration purposes only.

[0022] The removable assembly system 1 according to the invention makes it possible to temporarily hang a device 2 of any type on the support 3. According to a preferred example of application, the removable assembly system 1 allows the hanging of a medical electronic device such as a medical monitor or advantageously, a display screen 2 intended to be connected to a medical endoscope of any type known per se. This display screen 2 can thus be temporarily fixed on the support 3 (perfusion stand or solution pole for example) in particular when using the medical endoscope to which the display screen 2 is connected.

[0023] As more precisely shown in the Figures 1 à 8 , the removable assembly system 1 comprises two independent parts, namely a male part I and a female part II intended to cooperate together to allow the device 2 to be fixed to the support 3. In the embodiment illustrated in the drawings, the device 2 is provided with the female part II while the support 3 is provided with the male part I. Of course, another variant embodiment can be provided for which the device 2 is provided with the male part I while the support 3 is provided with the female part II.

[0024] As more precisely shown in the Figure 4 , the male part I comprises an arm 5 having a free end 6 and extending longitudinally along a longitudinal axis which will be called the insertion axis X in the remainder of the description. The free end 6 of the arm 5 is provided with a series of bearing teeth 7 extending perpendicularly to the insertion axis X. The bearing teeth 7 extend radially in a radial plane P perpendicular to the insertion axis X. In the example illustrated in the drawings, the arm 5 has a tubular shape of circular section but it is clear that the arm 5 can have a different shape.

[0025] The support teeth 7 are distributed around the periphery of the arm 5 according to a determined angular distribution, preferably regular. According to the example illustrated, the arm 5 is equipped with four support teeth 7 angularly offset two by two by 90°. It is clear that the number of support teeth 7 may be other than four and may be for example between 2 and 10. Two neighboring support teeth 7 delimit between them a passage hole 8. In the example illustrated, the free end of the arm 6 comprises four support teeth 7 delimiting four passage holes 8.

[0026] The angular width of the support teeth 7 can take different values adapted so that the support teeth 7 ensure their locking function as will be better understood in the remainder of the description. Preferably but not exclusively, the angular width is identical for all the support teeth 7. For example, the angular width of a support tooth 7 is equal to a value between 0.5 and 0.9 times the angular width of a passage hole 8.

[0027] Each support tooth 7 is delimited by an external edge 7e. Each support tooth 7 can have any shape. In the example illustrated, each support tooth 7 has a substantially rectangular shape. According to this example, the external edge 7e of each support tooth 7 comprises on either side, two radial parts 7r connected to each other by a peripheral part 7p.

[0028] According to an advantageous embodiment variant, the peripheral part 7p of the external edge 7e comprises, from each radial part 7r, a support ramp whose height relative to the arm 5 increases towards the middle part of the peripheral part 7p. The two support ramps meet in the middle of the peripheral part 7p of the external edge 7e, at the level of a stop groove 7a whose function will appear more precisely in the remainder of the description.

[0029] The female part II comprises at least one locking plate, for example in the form of a locking disc 10 delimited by a front face 11 and a rear face 12, and in which an opening 13 is provided with a section adapted to allow, in an insertion position, the engagement from the front face 11, of the free end 6 of the male part II beyond the rear face 12. The front faces 11 and rear faces 12 are taken into consideration of the position of the male part I relative to the female part II, before the insertion of the male part I into the female part II.

[0030] In other words, the front face 11 corresponds to the face facing outwards such as the external face of the rear wall of the device 2 in the illustrated example while the rear face 12 corresponds to the internal face of the rear wall of the device 2. The insertion of the male part I into the female part II is carried out by a relative displacement along the insertion axis X, between the male part I and the female part II. To obtain this insertion, the male part is displaced relative to the female part, the female part is displaced relative to the male part or the male part and the female part are displaced simultaneously.

[0031] As an example in the remainder of the description, the direction of engagement is noted by the arrow F1 and corresponds to the movement of the female part II to obtain the insertion of the male part I into the female part II, from the front face 11 of the female part ( Figure 5 ). Conversely, the direction of release is noted by the arrow F2 and corresponds to the movement of the female part II to obtain the withdrawal relative to the male part, of the female part II in a direction opposite to the direction of engagement F1.

[0032] To allow the insertion of the male part into the female part, it must be understood that the passage section of the opening 13 of the locking disc 10 is greater than the section of the free end 6 of the male part II, taken in the radial plane and formed by the section of the arm 5 and by the section or surface of the support teeth 7. In other words, the section of the free end 6 of the male part II taken in the radial plane comprising the arm 5 and the support teeth 7 is included strictly in the passage section of the opening 13.

[0033] The opening 13 is provided in the disc 10 to delimit radially extending retaining teeth 15 ( Figure 3 ). The retaining teeth 15 are distributed along a circumference of the disc 10 with a determined angular distribution, preferably regular. According to the example illustrated, the disc 10 is equipped with four retaining teeth 15 angularly offset two by two by 90°. It is clear that the number of retaining teeth 15 may be other than four and may be for example between 2 and 10. According to the exemplary embodiment, the female part II comprises a number of retaining teeth 15 equal to the number of support teeth 7 of the male part I. Of course, the number of retaining teeth 15 may be different from the number of support teeth 7 of the male part I.

[0034] Each retaining tooth 15 is delimited by an external edge 15e. Each retaining tooth 15 can have any shape. In the example illustrated, each retaining tooth 15 has a substantially rectangular shape. Two neighboring retaining teeth 15 delimit between them a notch 16 for passage for a support tooth 7 of the male part I. According to an advantageous embodiment characteristic, the angular width of a notch 16 taken between two neighboring retaining teeth 15 is equal to a value between 105 and 200% of the angular width of a support tooth 7.

[0035] Thus, when the male part I is engaged in the female part II along the insertion axis X, the distal end 6 is able to pass through the opening 13. Thus, the support teeth 7 pass through the opening 13 via the notches 16 while the holes 8 allow the passage of the retaining teeth 15. The support teeth 7 can thus extend beyond or behind the rear face 12 of the locking disc 10 so as to allow relative rotation between the male part I and the female part II around the insertion axis X. Of course, the female part II delimits, from the rear face 12 of the locking disc 10, a clearance allowing the positioning and rotation of the free end 6 of the arm 5 provided with the support teeth 7.

[0036] The retaining teeth 15 are arranged so that after a relative rotation between the female part II and the male part I, at least one and preferably all of the support teeth 7 are able to be positioned at least partly opposite the retaining teeth 15 to prevent disengagement between the male parts I and female parts II, in the disengagement direction F2 opposite the insertion direction F1 ( Figure 6 ). According to the preferred embodiment illustrated in the drawings, each retaining tooth 15 is locked by a support tooth 7 for movement of the female part II in the release direction F2. When the male part I and the female part II occupy this position, the removable assembly system 1 is in a translational locking position.

[0037] According to the invention, the female part II comprises a stop bottom 18 for the male part I limiting the engagement of the male part beyond the rear face 12 of the locking disc 10. This stop bottom 18 is positioned to allow the positioning of the support teeth 7 behind the retaining teeth 15 while remaining in contact or in support with the latter. This stop bottom 18 can exert a support force in the direction opposite to the direction of insertion to ensure support of the support teeth 7 against the retaining teeth 15. This stop bottom 18 has a compression capacity due to its constituent material or is stressed by a spring member for example.

[0038] According to the invention, the stop bottom 18 has a rotational guide surface between the male part I and the female part II in order to allow the passage from the insertion position to the locking position and vice versa. For example, the stop bottom 18 is produced by a circular stud of conical shape on which the distal end of the tubular arm 5 rests, promoting the rotational guidance and the centering in approach of the two parts, namely the male part and the female part.

[0039] According to another characteristic of the invention, the female part II and the male part I comprise an angular locking device 21 capable of angularly locking the female parts II and male parts I when they occupy the locking position. According to the exemplary embodiment illustrated in the Figures, the angular locking device 21 comprises a latch 22 mounted radially movable on the rear face 12 of the locking disc 10. Advantageously, this latch 22 is mounted to extend vertically, directly above the middle of a retaining tooth 15 and preferably, of the retaining tooth 15 located at the highest level vertically. As can be seen from the figures, the latch 22 extends radially back from the inner edge delimited by the opening 13 and in particular by a retaining tooth 15 and also back from the outer edge of the locking disc 10 so that the latch 22 is completely invisible from the front face 11 of the locking disc 10.

[0040] This latch 22 is provided with a member 23 allowing it to be moved in translation and positioned to be accessible from the front face 11 of the locking disc 10. For this purpose, the latch 22 is provided with a rod 24 connected to the displacement member 23 extending projecting relative to the front face 11. The rod 24 passes through an oblong slot 26 made in the locking disc 10 to allow the radial displacement of the latch 22. The latch 22 is intended to cooperate by its terminal part, with a support tooth 7 to ensure the rotational locking of the male part I relative to the female part II. As will be explained in the remainder of the description, the displacement member 23 is intended to be moved to unlock the rotational locking.

[0041] According to the invention, the latch 22 is intended to engage in the stop groove 7a of the corresponding support tooth. During the relative rotation between the male and female parts, the latch 22 is in contact with the external edge 7e of a support tooth 7 and engages in the stop groove 7a to block the rotation ( Figure 7 ). The latch 22 automatically engages in the stop groove 7a under the effect of its weight or the latch 22 is elastically biased by a spring member in its maximum extension position so as to be progressively compressed when it is resting on the ramp of the external edge 7e until it automatically engages in the stop groove 7a. The angular locking is carried out automatically during the relative rotation between the male and female parts.

[0042] Of course, the rotational release of the male part I relative to the female part II consists of lifting the actuating member 23 to release the latch 22 from the stop groove 7a ( Figure 8 ). It then becomes possible to turn the female and male parts relatively to each other.

[0043] In the illustrated embodiment, the latch 22 comprises a projecting end portion intended to engage in a stop groove 7a. Of course, the latch 22 may have an end portion produced with a different shape, for example, in the form of a claw engaging on either side of a bead carried by the support tooth 7. In an example which is not covered by the claims, the angular locking device 21 may be different from a latch acting radially and vertically on a support tooth 7. Thus, the angular locking device 21 may be produced, for example, by a latch acting axially to engage in a hole provided in the support tooth 7 placed in correspondence.

[0044] The implementation of the removable assembly system 1 according to the invention follows directly from the preceding description. The assembly of the male part I with the female part II consists of positioning the terminal end 6 of the male part in front of the front face 11 of the female part, by aligning the support teeth 7 of the male part I with the notches 16 of the female part II ( Figure 5 ). The relative movement in the direction of engagement F1 along the insertion axis X, between the male part I and the female part II causes the male part I and the female part II to occupy an insertion position in which the support teeth 7 extend beyond or behind the rear face 12 of the locking disc 10 ( Figure 6 ). Advantageously, the final insertion position along the insertion axis X is given by the end part 6 of the male part I coming into contact with the stop bottom 18 of the female part II. The male part I and the female part II are therefore locked in the direction of engagement F1.

[0045] In this final insertion position, a relative rotation between the male part I and the female part II causes the latch 22 to come into contact with the outer edge of the corresponding support tooth 7. During this rotation, the latch 22 is gradually lifted by the ramp arranged on the outer edge 7e and automatically engages in the groove 7a. In this position, the male part I and the female part II are therefore locked in relative rotation. Also in this position, the support teeth 7 are located opposite the retaining teeth 15 so that the male part I and the female part II are locked in the release direction F2. In the position illustrated in Figure 7 , the male part I and the female part II are assembled together by a complete connection by the system according to the invention.

[0046] The separation between the male part I and the female part II is achieved by carrying out operations reverse to those described previously. The latch 22 is lifted using the displacement member 23 accessible from the front face 11, to release it from the support tooth 7 ( Figure 8 ) allowing relative rotation between the male part I and the female part II until the support teeth 7 are positioned opposite the notches 16. The relative movement in the release direction F2 along the insertion axis X, between the male part I and the female part II causes the male part I and the female part II to occupy a release position in which the support teeth 7 extend beyond or in front of the front face 11 of the locking disc.

[0047] The removable assembly system 1 according to the invention makes it possible to ensure a removable assembly of a device 2 on a support 3 of any type known per se. According to a preferred application, the support 3 relates to the medical field while the device 2 is a display screen intended to be connected to a medical endoscope of any type known per se. According to the example illustrated in Figure 1, the display screen 2 is equipped with the female part II. For this purpose, the display screen 2 comprises a housing 2 1 having a front face 2a and a rear face 2b extending substantially opposite the front face 2a. The housing comprises a lower edge 2c and opposite an upper edge 2d. This lower edge 2c and the upper edge 2d are connected to each other by two lateral edges 2e. A part of the rear face 2b is provided with the locking plate 10 with its front face facing the outside of the housing while the stop bottom 18 is mounted inside the housing. The locking plate 10 is for example fixed by screws 10v on the rear face 2b of the housing. Advantageously, the locking plate 10 is mounted so that the displacement member 23 of the locking latch 22 is positioned preferably close to the upper edge 2d of the housing.Such positioning allows the latch to be unlocked by lifting it and the screen to be picked up simultaneously with one hand.

[0048] It is clear from the above description that the subject of the invention also relates to equipment comprising an apparatus 2 assembled to a support 3 in the general sense using a removable assembly system 1 according to the invention. The apparatus 2 is equipped for example with the female part II while the support 4 is provided with the male part I. The apparatus 2 can be easily mounted and dismounted relative to the support 3.
